3. Configure the priority used to determine the stack master and standby roles in the stack, where
stack-unit 0 is the default stack-unit number.
CONFIGURATION mode
stack-unit 0 priority value
• stack-unit 0 is the default stack-unit number.
• priority value specifies the management priority.
The range is from 1 to 14.
The default is 0. The unit with the highest priority is elected stack master.
4. Repeat Steps 1 to 3 on each stack unit to pre-configure the election of master and standby stack
units.
5. Assign a number to the stack unit,
EXEC Privilege
stack-unit 0 renumber unit-number
• stack-unit 0 is the default stack-unit number.
• stack-unit unit-number is the new stack-unit number. The valid values are from 0 to 11.
After you reconfigure the unit number, you are prompted to reload the switch. Type yes to confirm;
type
no to exit.
Before the switch reloads, you are prompted to save the configuration. Type yes to confirm and to
reload the switch.
6. Repeat Step 5 on each stack unit to configure the stack-unit number of the master, standby, and
member units.
7. Enable a group of four 10 GbE or a single 40 GbE port in stacking mode.
CONFIGURATION mode
stack-unit unit-number stack-group group-number
• stack-unit unit-number is the stack-unit number.
• stack-group group-number is group of four 10 GbE ports or one 40 GbE port. The valid
values are from 0 to 15.
8. Save the stacking configuration to the startup configuration.
EXEC Privilege mode
write memory
9. Repeat Steps 7 and 8 on each stack unit to configure the stack ports on the master, standby, and
member units.
10. Reboot each switch, one after another, in as short a time as possible.
EXEC Privilege mode
reload

Dell Networking OS Behavior: After you configure the 10 GbE ports in a stack group for stacking, you
cannot use the ports for Ethernet data transmission. For example, if you enable stack group 0 for stacking
